As the impact of population aging becomes increasingly serious, more problems emerge with regard to medical and long-term care for the older individuals, which require solution. In long-term care, accidental falls frequently occur and are a significant cause of serious injuries and bed confinement due to leg fractures. Older people are especially prone to fall out of bed when they try to get up on their own. To reduce the occurrence of such accidents, one important solution is to detect the getting-up behavior of older individuals and to alert nursing staff to come and check. Although many studies have proposed various solutions such as the use of wearable devices and vision-based sensors, there are many issues in practical application. The complexity of device installation, high initial cost, and maintenance problems have restricted most care facilities to using fall prevention systems with mediocre results, such as pressure pad sensors. In this paper, we propose a fall prevention system based on a single camera (with infrared function) and infrared reflective sheets (IR sheets). The system detects the IR sheets placed on the shoulders of an individual and obtains position data. The relative positions of the IR sheets can be used to identify the state of the person on the bed. To improve the identification ability of the system, we propose to define an identification area. To identify the state more accurately, we propose to establish sub-areas within the identification area. We conducted experiments by recruited 19 subjects. The data of 6 subjects were used to construct the sub-areas. The other 13 subjects participated in testing the ability of the system in identifying the various states of the person in bed. Compared with the performance of other studies, our experimental results demonstrate that our system has a high identification rate, in addition to being low-cost and easy to set up.

Most sports-assisting technologies have been developed to improve performances only in individual sports such as skiing, batting, and swimming. In team sports, it is important to perceive one's position relative to others. Few studies have focused on team sports, which not only require the motor ability of individual players, but also their perceptual abilities. This pilot study aimed to evaluate the effectiveness of a visual feedback system to improve players' spatial perception relative to others. The visual feedback system was composed of a flying drone that transmitted an image to the participant's smart glasses. The participant was able to see his/her own relative position in real time using the glasses with and without the system. Nine participants tried to position themselves on an imaginary line between two experimenters 30 m away from each other, which simulated the situation of a baseball cutoff man. The results showed that the error in distance between the participants' positions and the line decreased significantly when using the system compared to when not using it. Furthermore, there was also a reduction in positioning error in subsequent trials after participants performed the task using the system, compared to before they used the system. In conclusion, the real-time feedback system from a bird's-eye view has the potential to improve accuracy in spatial perception.
